Took less than 5 minutes to configure my Cisco 100 Gb port to provide Ethernet to four 25 Gb Mellanox ConnectX-6 ports in various computers. I own both the 100 Gb to four 25 Gb and 100Gb to four 10 Gb cables. Great products.

I have a Unifi Pro Aggregation switch with 4x SFP28 and these cables work great!

This cable seems nice and works for my current situation, however when I tested it with my HPE switches, it did not work.

Exactly what I needed; just some short 25G TwinAx to connect a file server/NAS/Block to a network and increase performance.NIC was sourced off Amazon, a dual port 10/25 QSFP, and the other end is a Ubiquity XG Pro Aggregation switch. Seems stable and error free. Just plug in and go!

I have one end in an SFP+ jack and the other in an SFP28. Works as expected at 10Gb, haven't tried 25Gb yet but I doubt it'd be a problem.

I’ve had great success with the 10GB DAC cables that I decided to try their SFP28 cables for the shirt 0.25 nodules. Just like the 10GB cables, these worked without an issue.

I needed a 25G cable for a pair of HPE DL360 Gen 10 servers used for my home PLEX setup. The HPE servers are using HPE 640FLR-SFP28 network cards and my late night tech support request .... PRE SALE support to find if they offered a HPE solution was answered the same night, within hours, that the CISCO variant was compatible. This is great information for future purchases and to help others. I received the cable today and rigorously tested it. Amy at 10Gtek went the extra mile to help me find an inexpensive solution. My only advice is to buy the cable a pinch longer than you need, I ordered .5M and if I did it again I would have ordered 1M.
